lol, I'm definitely biased given that I'm long since familiar with the idea and wrote the implementation, but I think it's more conceptually counterintuitive/clever/weird than it is actually complicated in terms of having many moving parts. WebSign does have a patent pending on it (I think it's fair enough to say that the whole system of accomplishing in-browser code signing this way was non-obvious), but HPKP Suicide itself doesn't. Bryant (eganist) and I are actually disclosing and open sourcing implementations of a few non-code-signing applications of HPKP Suicide at Black Hat and DEF CON next month.
